A series of three-dimensionally ordered macroporous (3DOM) alumina doped phosphotungstic acid (HPW)/TiO2 materials was synthesized successfully through sol–gel method with highly ordered 3D polystyrene monoliths as macroporous template. The characterization results of scanning electron microscope and transmission electron microscopy upheld the existence of periodically arranged macroporous structure...
A series of amphiphilic hierarchically meso/macroporous phosphotungstic acid (HPW)/SiO2 materials have been synthesized via a facile post treatment strategy and used as a catalyst for oxidative desulfurization (ODS). The SEM and TEM images revealed that as-prepared catalysts possessed a well-defined meso/macroporous structure and the average pore size of macropores and mesopores were estimated to...
